To all whom it may concern:

Be it known that I, MATHIAs B. BECKER, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Methods of Ornamenting Prepared Roofing; and I do hereby declare the followin to be a full, clear, and exact description o the invention, such as will enable others skilled in the art to which it appertains to make and use the same. v

This invention has for its object to pro vide a novel method ofproducing prepared roofing andy consists in the steps hereinafter fully described and claimed.

In the accompanying drawings: Figure 1- is a view in central vertical longitudinal section of a machine employed in carrying out my said process. Fig. 2- is a fragmentary view in elevation of roofing prepared in accordance with my process. F1g. -3- is a detail sectional view of the roofing on the line 33 of Fig. 2.

The object of my present invention is to provide a process for treating prepared roofing whereby a design in different colors is produced thereon while at the same time the life and wearing qualities of the roofing are materially increased. The product resulting from carrying out this process is fully described and claimed in a companion application tiled of even date herewith, Serial No. 674,821.

Prepared roofing usuali consists of a sheet or web A of wool felt or other brous material which is impregnated with and provided with surface 'coatings B and C of asphaltum. Upon the coating B there is applied a covering of granulated grit pan ticles D such as gravel, crushed stone or slate which is applied while said coating is hot and soft and becomes partially embedded therein. rllhe character or color of such grit determines the color of the roof to which the material is applied, such color being uniform and rather monotonous in appearance.

My said process consists in applying upon certain predetermined fields of the grit coated surface of the rooing a li uid having the quality of being water-proof when dry and capable of adhering to the asphaltum coating in which the grit is partially embedded and in such lquantity as to substantially embed said grit coating and be come amalgamated or homogeneous vwith the asphaltum coating underneath the same so as to so completely and thoroughly at tach such grit to said asphaltum coating as to prevent the same from being washed away by rain or carried away by snow and ice.

In carrying out my process I prefer to employ a dilute asphalt-um, that is asphallatter becoming thoroughly admixed and intermingled with said asphaltum immediately upon cont-act of the two, it being obvious, of course, that a relatively large proportion of said benzin or creosote will pass off in vapor while the process of commingling is going on. The resulting liquid consistsl substantially of seventy (70) per cent., more or less7 asphaltum and thirty (30) per cent., more or less, creosote or benzin, depending upon which of these two substances is used.

Benzin and creosote are known solvents of asphaltum and the resulting mixtures when applied either hot or cold to the asphaltum surface of the prepared rooting will cause the latter to partially dissolve and when dry the coating E applied in liquid form lwill become substantially homogeneous and firmly amalgamated with the asphaltum coating of the prepared roofing.

The fluent asphaltum may be applied upon the grit coated surface of the prepared roofing in any desired manner, as for example, by means of stencils or by means of an ordinary paint brush either with or with out the use of a 4stencil. However, this method of applying the same is necessarily very expensive and would so increase the cost of the roofing as to render it prohibitive in competition with the more expensive and more attractive kinds of roofing.

In order to cheaply produce the design on the roofing in such a manner as to cause the amalgamation before referred to to be .l i effected, Iprefer to employ a machine for 'the purpose 3 which is fully described in a companion application filed' of even date herewith Serial No. 674,819. The said machine is equipped with a rotating cylinder l having its surface divided into fields of such l means of a second cylinder 3 bearing on the other face of the roofingl and serving to compress the same against said pads 2. Below` t-he cylinder l there is mounted a pan 4 containing the dilute asphaltum in which the pads 2 carried by the cylinder become immersed during therevolution of the cylinder/and of which they absorb af relatively large quantity.. As saidl pads 2 are com- L pressed against thegrit coated surface of the roofing, the grit particles embed them- ,selves in the surfaces of said'pads and by the compression of thelatter the liquid is expelled as from a sponge and thus a suiicient quantity applied to the grit coated surface to completely coat each grit particle and penetrate through the grit coating into con j tact with the asphaltum coating with which it amalgamates and becomes homogeneous.

' -The dilute asphaltum is preferably applied cold to the cool rooting but if found desirable either vor both may be heated without departing from the invention.

Thel dilute asphaltum is black and will produce black yfields on grit coating. Any otherv color of liquid having` substantially the same properties maybe substituted for the dilute asphaltum without departing from the invention.

I claim as my invention:

1. The hereindescribedv method of ornamenting prepared asphaltum roofing having a grit coated surface, which consists in applying on various parts of the grit coated surface a solution of a substance having the propertyvof dissolving the asphaltuml coating and in drying to become amalgamated therewith, said solution being waterproof when dry and being of a different color from the grit .and applied in such quantity as to cover 'and penetrate through said grit coating and envelop the grit particles.

2. The hereindescribed methodV of ornaf. menting prepared asphaltum roong having a gritcoated surface, which consists in applying on various parts of the grit coated surface a cool solution of a substance having the property of dissolving the .asphaltum coating and in drying to become amalgamated therewith, said solution bein waterproof when dry and being of a iiferent color from the grit and lapplied in such quantity as to cover and penetrate through saidgrit coating and envelop the grit particles. v l

3. 'Ihe hereindescribed method of ornamenting prepared asphaltum roofing having a` grit coated surface, which consists in applying on various parts of the'grit coated surface of the roofing when cool, a cool soluy.

tion of a substance having the property of dissolving t-he asphaltum coating and in drying to become amalgamated therewith;

vsaid lsolutionv being waterproof when vdry and beiner of a different color from the grit and app iedin such quantityy as tol cover and penetrate through 4said grit coating and envelop the grit particles. v 1
